For ME EQUIPMENT and ME SYSTEMS that are not LIFE-SUPPORTING
Guidance and manufacturer's declaration – electromagnetic immunity
The SBC 23 is intended for use in the electromagnetic environment specified below. The customer or the user of the SBC 23 should assure that it is used in
such an environment.
Immunity test IEC 60601 test level Compliance level
Radiated RF 3 V/m 80 MHz to
IEC 61000-4-3 2.5 GHz
NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and
people.
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM
a
radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmit-
ters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the SBC 23 is used exceeds the applicable
RF compliance level above, the SBC 23 should be observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating the SBC 23.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1] 3 V/m.
b
Electromagnetic environment – guidance
Portable and mobile RF communications equipment should be used no closer to any part of
the SBC 23, including cables, than the recommended separation distance calculated from the
equation applicable to the frequency of the transmitter.
Recommended separation distance:
d = 1.2
d = 2.3
3 V/m
Where P is the maximum output power rating of the transmitter in watts (W) according to the
transmitter manufacturer and d is the recommended separation distance in meters (m).
Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey,
should be less than the compliance level in each frequency range.
Interference may occur in the vicinity of equipment marked with the following symbol:
80 MHz to 800 MHz
800 MHz to 2.5 GHz
